Accelerometer mount for ender

Needed a sturdy mount for the portable accelerometer. A weak mount will affect the measurement and beeswax is also not an option :)

I am running the printer on marlin but made a simple klipper setup just with the x,y,z motion to measure the resonance. To verify the values found with the manual test print.
Now I just swap sd cards between marlin and klipper.

It seems that marlin is improving the input shaping feature: https://marlinfw.org/docs/gcode/M493.html

Configuration: https://github.com/FYSETC/FYSETC-PortableInputShaper

Uploaded also the klipper config files rename them to .cfg
